I should probably say more. This is a 250 Hz CW filter for the first IF
of the OMNI-A/D (C) and for the OMNI V, VI and Paragons. It has a lower
center frequency and works very, very well. It is the only Ten Tec
(Network Sciences) filter I prefer over the INRAD offerings. It produces
very little ringing and helps dig down into the noise.
